What Is the Origin of the Calendar?

The Maya sacred calendar is called Tzolk’in in Yucatec Mayan and Chol Q’ij in K’iche’ Mayan. This calendar is not divided into months. Instead, it is made from a succession of 20 day glyphs in combination with the numbers 1 to 13, and produces 260 unique days. Multiplying 20 x 13 equals 260 days. This image illustrates how the numbers 1 to 13, cycle through the 20 glyphs to form dates in the Tzolk’in calendar. Any such combination, such as 1 Imix’, repeats only after 260 days have passed. The length of the Tzolk’in matches nine cycles of the Moon and the gestational period of humans. The Tzolk’in is also related to the movements of the zenith Sun and the growing cycle of corn. https://maya.nmai.si.edu/calendar/calendar-system#:~:text=The%20Maya%20sacred%20calendar%20is,x%2013%20equals%20260%20days.
